Revision of the enigmatic Southeast Asian spider genus Savarna (Araneae, Pholcidae)

Abstract

Abstract. The genus Savarna Huber, 2005 was previously one of the most poorly known Pholcinae genera. Less than 20 specimens (representing four nominal species) were available worldwide; nothing was known about ultrastructure, natural history, or relationships. We present the first SEM data, supporting the position of the genus in Pholcinae outside the Pholcus group of genera and weakly suggesting a closer relationship with the genera Khorata Huber, 2005, Spermophorides Wunderlich, 1992, and two undescribed species of unknown affinity from Borneo. We provide the first data about microhabitat, web structure, and reaction to disturbance. We clarify the type locality of Savarna tessellata (Simon, 1901) ("Jalor, Biserat") and describe topotypical material. We describe the previously unknown male of Spermophora miser Bristowe, 1952 and transfer the species (that was previously considered incertae sedis) to Savarna as Savarna miser (Bristowe, 1952) comb. nov. Savarna baso (Roewer, 1963) is newly synonymized with S. miser. We describe the most northern species in the genus, Savarna kaeo sp. nov., and provide amendments to the descriptions of all previously described species.

A new genus of ground and litter-dwelling pholcine spiders from Sarawak (Araneae, Pholcidae)

“…Bor20" in Huber et al 2015a) were not only different from Aetana in many details, but, in fact, closer to Khorata and Savarna. At the same time, the two species do not share any of the distinctive characters of Khorata (Huber 2005b) and Savarna (Huber 2005b;Huber et al 2015b). As a consequence, they are here described as representatives of a new genus.…”

Review of the millipede genus Malayorthomorpha Mršić, 1996 (Diplopoda, Polydesmida, Paradoxosomatidae), with descriptions of two new species from Thailand and a key to its species
